APPARATUS FORIDRYING ARTIFICIAL SILK, YARN, OR THE LIKE.

Application filed March 20, 1926. Serial No. 96,359.

This invention relates to a new and im- -proved apparatus for use particularly inv drying skeins of artificial silk, hanks of yarn in dyeing operations, and. for other a and analogous purposes.

The objects of the invention are to improve upon existing structures for this purpose, to obtain more satisfactory results and to improve the character of the product ob- 1e tained. It is also a purpose of the invention to avoid certain disadvantages connected with the use of former types of apparatus.

The invention has for its purpose the construction of an improved pole which is used for the support of skeins of artificial silk known in the trade as rayon during the drying. It is also for use in the dyeing industry for the support of hanks of yarn While drying. The invention is, therefore,

' in a construction of a dye pole, as it is mown in the trade, although its use is not necessarily so limited but may be extended to other fields and arts.

Dye poles of the prior art have been 26 made either of wood or glass. The first form of pole is unsatisfactory for many reasons, principall due to the chipping of the poles and the act that fragments of wood will be caught in the hanks of yarn. Wooden poles are also unsatisfactory because of the fact that they become stained and will discolor delicate yarns and threads and are therefore unsuitable for some of the higher grades of work. Glass poles are expensive and fragile and, in addition, will chip easily, the sharp edges causing the yarns or threads to be cut. The improved form of pole shown herein overcomes the disadvantages and dificulties attendant upon the use of wooden or glass In the drawings: Figure 1 is a view of a dye pole in posit1on upon a conveyor;

Figure 2 is a cross-section on the line Figure 3 is a fragmentary, longitudinal sect on on the line 33 of Figure 2;

Figure 4 is a cross-section through an end of the pole.

The dye pole is adapted to be supported upon any suitable form of conveyor, a fragment of one being shown in Figure 1, in which the conveyor chain is shown at 1 and the pockets or holders for the reception of the poles at 2.

The pole comprises a seamless steel tube 5 WhlCh is for the purpose of giving rigidity and strength to the pole. The body of the pole is enclosedwithin a jacket 6 of hard rubber composition which is permanently vulcanized to the steel pole. A coating or film of cement -7 may be applied to the pole beforethe hard rubber jacket is vulcanized 1n positlon, whereby the adhesion between the pole and the jacket will be assured.

At its central portion, over which the material to be dried is suspended, the pole is formed with a plurality of flutes or grooves 10 which are separated by ribs 11. The material hanging over the poles is indicated at 12 and it will be apparent that as the material is supported upon the ribs, the grooves or flutes will permit the liquid with which the material is saturated to drain out into the flutes. This is advantageous as it permits all of the material, both that in contact with the pole and. that depending from I it, todrain.

The flutes extend along the entire portion of the pole upon which the material is suspended, but in order to prevent the liquid from draining to the ends of the poles and running onto the conveyor, the poles are formed with barriers, such as enlarged bulbed formations 15, at the ends of the flutes and somewhat larger than the ribs, so

that the liquid is intercepted and will drain ofi the enlargements 15.

These poles are roughly handled, being often dropped on their ends, and it is advisable to provide a different material at the ends of the poles than the brittle, hard rubber which covers the body of the pole.

' 17 therefore, serve to support the tube 5 in the mold while the jacket -6 is being vulcanized about it, and so support and center the tube. In order to firmly umte the plu a. series of holes 18 are formed around the tube and rubber from the outer jacket will flow into these holes during vulcanization and knit with the projection 17, thereby firmly anchoring the plug in position. The fibrous composition of the plug also prolongsthe life of the dye pole and withstands the abrasion from the conveyor.

It will be observed that a highly satisfactory and eflicient form of dye pole has been provided. ,Theouter jacket of hard rubber will withstand acids and alkalies alike and will not discolor the most delicate materials; It is easily kept clean and the fluted formation will materially aid in drawing ofi the liquid with which the material 1s saturated. lit will withstand the hard'usage and will not injure or cut the most delicate threads. The steel tube in the center of the pole makes it rigid and. it will not sag or warp.

What is claimed is:

1. A dye pole for use 1n drying materials such as yarns or artificial silks, comprisinga steel tube a hard rubber jacket surround ing the tube and vulcanized thereto, the outer surface of the jacket being provided with horizontal rooves, an enlar ed formation at the end 0 said grooves, an a cushion plug at the end 6f the pole.

2. A pole for the uses and purposes set forth, comprising a rigid reenforcing member and a 'acket of hard rubber permanently vulcanized to the reenforcing member.

3. A pole for the uses and purposes set forth, comprising a rigid. reenforcing member and a jacket of hard rubber permanently vulcanized t0 the reenforcing member, the surface of the pole being formed with spaced longitudinal ribs to support the material spaced from the body of the pole.

, 4. A pole for the uses and purposes set forth, com rising a rigid reenforcing member centra ly located in the ole, a jacket of hard rubber ermanent y vulcanized about the\ pole, an cushions secured in the ends of the pole.

'5. A pole for the-uses and purposes set forth, comprising a rigid reenforcing memmesses ber centrally located in the ole, a jacket of hard rubber about the po e, and cushion members of rubber composition located at the ends of the pole, the rubber being vulcaniz'ed permanently to the surface; of the reenforcing member.

6. A pole for the uses and purposes set forth, comprising a steel tube a jacket of hard rubber surrounding the tube, and plugs of cushion rubber inserted within the ends of the tube, the rubber being vulcanized permanentl to the surface of the tube.
